Filed: 1972-01-13
Abstract: 1362471 Vehicle suspensions G FUCHS and U THIERER 13 Jan 1972 [14 Jan 1971] 1673/72 Heading B7D In a mobile working machine such as a crane or excavator having a frame 1 in the form of a hollow box member and front wheels 3 connected to pivoted control arms 21 adjustable by means of hydraulic rams 41 for varying the wheel height and track width, the rams 41 are disposed in the hollow space within the frame 1 and connected in each case by an angle lever 45 and a transverse link 48 to the respective arm 21. The rams 41 are longitudinally arranged within the frame 1 and anchored to a yoke member 14 which is detachably fitted into the end of the front portion 11 of the frame 1 to provide for removal of the rams. The control arms 21 are connected to a cast steel supporting portion 12 of the frame 1 by longitudinally aligned hinge joints 23 and to stub axles 4 for the wheels 3 by universal joints 22. Camber-adjusting cylinders 24 extending between the stub axles 4 and the arms 21 are connected to control cylinders 51 in the frame 1 so that the wheel camber remains constant throughout the range of adjustment of the arms 21. A longitudinally-extending link 27 is connected to the upper part of each stub axle 4 by a universal joint 28 and to a frame part by a universal joint 29. Each wheel 3 is steered about an axis passing through the joints 22, 28 by a steering link connected by a universal joint 31 to an arm 32 on the stub axle 4.

Patent GB-138090-A (GB)
Title: Improvements in speedometers for vehicles and the like
IPC: G01P1/04
Filed: 1920-01-20
Abstract: 138,090. Dayton Engineering Laboratories Co., (Assignees of Kettering, C. F.). Aug. 28, 1918, [Convention date]. Speed-indicator transmission mechanism; magnetic speed indicators.-In speed-indicating apparatus, means are provided whereby the movement of a vehicle is communicated indirectly to a speed indicator of the magnetic-drag type through an electric motor, the speed of which is governed by the speed of the vehicle by means of a rheostat driven by the motor and a contact carried by an escapement device controlled by a magnet energized intermittently from the vehicle wheel, this mechanism operating as a hunting switch. In the form shown in Figs. 1, 2, and 3, a motor 50 receiving current from a battery 110 serves to drive the shaft 42 of the speed indicator 40, the current being controlled by the frequency with which spring contacts 119, 120 are closed by a pin 122 on the vehicle wheel. Driven from the shaft 42 by reducing-gearing is a wheel 65 carried by a stub-shaft 66, on which is mounted a collecting-ring 72 in circuit with the commutator brushes 59, 60 and a rheostat 76 carried by an insulating-ring 75. Also mounted on the shaft 66 is an escapement device comprising two wheels 81, 85 connected by a spiral spring 88 and a pin 83 on the lower wheel engaging a slot 86 in the upper wheel. A wiper contact 78 adapted to move over the rheostat is carried by the underside of the wheel 81, connexion between which and the disk 72 is effected by a spiral spring 91. Pallets 102, 103, pivoted on a post 100 on the base-plate 47, are provided to engage the wheels 81, 85, a spring 106 serving normally to hold the pallet 102 in engagement. Formed in one with the pallets is the armature 101 of an electro-magnet 104 which is in circuit with the battery and the contacts 119, 120. In operation, when the vehicle is at rest, the contact 78 is out of engagement with the rheostat 76 and situated at the right hand thereof as viewed in Fig. 1, the spring 91 being tensioned. As the vehicle wheel re volves, the contacts 119, 120 are closed, and the magnet energised to rock the pallets to lock the wheel 85 and free the wheel 81, which is moved by its spring 91 to bring the pin 83 to the lefthand end of the slot 86, thus causing the contact 78 to move over the rheostat and close the motor circuit. De-energization of the magnet causes the position of the pallets to be reversed by the spring 88 through the length of the slot 86. Simultaneously, the rheostat is rotated away from the contact 78 in a clock-wise direction, this sequence of events continuing until the motor shaft is revolving in consonance with the vehicle wheel. In a modified form of the apparatus, the escapement wheels are mounted concentrically with the motor shaft and the reducing-gearing between the motor shaft and the collecting-ring comprises internal epicyclic gearing operated by an eccentric on the motor shaft.

Title: Improvements in dye transfer processes particularly for colour photography
IPC: G03C7/25
Filed: 1955-01-21
Abstract: 763,797. Imbibition transfer process for monochrome and multicolour photography. KODAK, Ltd. Jan. 21, 1955 [Jan. 21, 1954], No. 1941/55. Class 98(2) A silver image in a developed and fixed emulsion layer is converted to a silver halide image, dyed, with a basic dye in the presence of a water-soluble halide, washed to remove excess dye and halide, and pressed while still moist into contact with a moist mordanted receiving sheet in the presence of a water-soluble silver salt for transfer of the dye image. Thus dye is absorbed on the halide image in the presence of soluble halide but is released by the silver salt. Repeated transfer may be effected after washing the emulsion to remove soluble silver salt and re-dyeing and treating with soluble halide. The process is particularly adapted for preparation of subtractively coloured dye images from silver colour separation negatives, thus in Example 1 the negatives developed to a gamma of about 0.5, after normal fixing and washing are treated in ferricyanidepotassium iodide bleaching bath and washed, the red separation is treated in a solution comprising acetic acid, potassium iodide and Malachite green or Rhodaline Blue 6GA, washed in dilute acetic acid, and rolled in contact with a receiving layer comprising deashed gelatin incorporating the sodium salt of phosphotungstic acid as mordant, and which has been soaked in silver nitrate solution containing acetic acid; the receiving layer is then reconditioned with acid silver nitrate solution and printed similarly from the green and blue separations using Astraphloxine FF and Acriflavine respectively as dyes. In a second example a receiving sheet prepared by coating a solution contaning hydrolysed 5 - [4 - (2:4 - di - tert - amylphenoxy) - 3 - (2 - hydroxy - 3:5 - dichloro - 4 - methylphenylcarbamyl) phenylcarbamyl] - 1 : 3 - benzene di-sulphonyl chloride as mordant, saponin as spreading agent and mucochloric acid as hardening agent and gelatin, on cellulose acetate film base, is first conditioned in a hardening bath comprising sodium hexametaphosphate, sodium bisulphite, sodium carbonate, sodium sulphate, potassium bromide and formalin, and then in an acetic acid silver nitrate bath, and is rolled in contact with a silver image treated as described for the red separation of Example 1 to demonstrate the effectiveness of the dye transfer. Numerous basic dyes and water soluble halides for application to the silver image and mordants for the receiving sheet are described.
